Be more precise with your problem description, please
I can't believe in a not valid IMG renaming, I'd rather follow the GMA file present in the device idea.
My unit does use an SD, a micro one to be exact. In this new model unfortunately there is no way to copy to internal memory.

I'm assuming the problem is with the GMA file because the only SD Card working properly has this file, all the others (all Garmin official) aren't.

Forgot to mention a folder named PNX (with a PNX file under it), what's it for?
